Couple with Advertising Umbrella on Beach Antique Photograph

I don't buy a lot of old photographs, but I could not resist this couple, perched on a rock under this terrific umbrella, which if one looks closely seems to advertise a store selling shoes and clothing in what I believe reads Hagerstown (Maryland.) I love how she grips one side of the umbrella while he sits relaxed with hands folded in his lap, and the contrast between his whites, her dark dress, and the alternating light and dark panels of the umbrella. 

Photo measures 3" x 3 1/4". It is mounted to a cardboard backing that measures 5"x5". There is a bit of aging to the photo visible in the sky, but overall very good condition.
